摘　　要：采用离子交换法对银杏壳中果胶进行提取。通过单因素试验和正交试验探讨了提取过程中各因素对果胶得率的影响,结果表明适宜工艺条件为:离子交换树脂用量7%,p H 2.0,提取温度85℃,提取时间2h,料液比1∶20(g∶m L)。在此工艺条件下,果胶得率为4.85%。The pectin of ginkgo biloba L. shells were extracted by ion-exchange method. The influent of single factors and orthogohal tests on the yield of pectin were studied. The results showed that the appropriate technical conditions were as followed： cation exchange resins 7%, pH 2.0, the extraction temperature 85 ℃ , the extraction time 2h, the ratio of material to extraction solution lg/20mL. Under the process conditions, the extract yield of pectin was 4.85%.
